Abstract (en)
To provide an information recording medium and an information processing apparatus and method in which the content usage by ensuring copyright protection can be implemented both in CD players and information processing apparatuses, for example, PCs. A license providing condition for a client can be dynamically set based on the content usage status of the client. For example, for clients having a large number of content usages, the license price is decreased, or the license can be provided free. A media ID stored in, for example, a CD, and a product ID as an identifier in, for example, a title unit or an album unit are received from the client. Based on such identification data, the content usage status data can be checked. Accordingly, the licenses can be provided under the reliable management of the content usage. <IMAGE>
